Abstract
AbstractFluctuation of crystallization was observed at floating molten zone under reduced gravity condition on airplane. The zone material was Ba(B0.9Al0.1)2O4. A pair of Pt tubes was used at the upper and the lower positions, and the molten zone was formed between two Pt tubes. Double peak temperature profile could be performed using two Pt tubes. Crystallization of the molten Ba(B0.9Al0.1)2O4 was started at center part of side surface of floating molten zone under reduced gravity condition. The formed crystal was melted again during the crystallization by the gravity fluctuation at the center part of the floating molten zone. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
